hi, we have a 05 N/A forester at work which we can not diagnose, it is mising/backfiring under load, but we cant figure out why.

sofar we can not diagnose one specific cylender missing by pulling the leads.

we have replaced:

-plugs

-leads

-coil pack

-MAF

-fuel pump

-fuel filter

plus a few more.

does anyone know what would be the problem?

will be changing the temp sensor troubleshooting the injectors soon

Checked for air leaks? Backfiring sounds odd...
